Benefits of technology

[0006]An object to be achieved by the present invention is to provide a medical apparatus and a method, which can grasp a position of a target of an object without a significant delay even when a fluoroscopic image needs to be corrected.
[0008]According to the present embodiment, it is possible to provide a medical apparatus and a method, which can grasp a position of a target of an object without a significant delay even when a fluoroscopic image needs to be corrected.

Problems solved by technology

The corrector corrects an image of one or more predetermined regions used for identifying a target position of the object in the fluoroscopic image based on one or more correction values but does not correct an image of at least a part of a region out of the predetermined region in the fluoroscopic image.

first embodiment

[0022]

[0023]FIG. 1 is a configuration diagram of a therapy system 1 including a medical apparatus 100 of a first embodiment. For example, the therapy system 1 includes a therapeutic device 10 and the medical apparatus 100.

[0024]For example, the therapeutic device 10 includes a bed 11, radiation sources 12-1 and 12-2, detectors 13-1 and 13-2, an irradiation gate 14, a sensor 15, and a therapeutic device-side controller 20. Hereinafter, a hyphen and a numeral following it in the reference sign indicate a fluoroscopic radiation or a fluoroscopic image realized by a set of a radiation source and a detector. Suitably, the hyphen and the numeral following it in the reference sign may be omitted in description.

[0025]An object P to be treated is fixed to the bed 11. The radiation source 12-1 irradiates the object P with a radiation r-1. The radiation source 12-2 irradiates the object P with a radiation r-2 at an angle different from that of the radiation source 12-1. The radiations r-1 and ...

second embodiment

[0116]Next, a medical apparatus 100A according to the second embodiment will be described. The present embodiment differs from the first embodiment in the fact that the reference image maker 132A has a learner 132a. However, configurations other than described below are substantially the same as the medical apparatus 100 according to the first embodiment.

[0117]FIG. 11 is a configuration diagram of the therapy system 1 including the medical apparatus 100A according to the second embodiment.

[0118]For example, the therapy system 1 includes the therapeutic device 10 and the medical apparatus 100A. The medical apparatus 100A has the reference image maker 132A in place of the reference image maker 132 of the first embodiment. The basic function of the reference image maker 132A is similar to that of the reference image maker 132.

[0119]In the present embodiment, the reference image maker 132A has the learner 132a. When a therapy is divided into a plurality of times (a plurality of days), t...

Abstract

A medical apparatus according to an embodiment includes an acquirer, a corrector, an identifier, and an output controller. The acquirer is configured to acquire a fluoroscopic image of an object from an imager. The corrector is configured to correct an image of one or more predetermined regions used for identifying a target position of the object in the fluoroscopic image based on one or more correction values but does not correct an image of at least a part of a region out of the predetermined region in the fluoroscopic image. The identifier is configured to identify the target position based on an image corrected by the corrector. The output controller is configured to output an irradiation permission signal to a therapeutic device which irradiates the object with a therapeutic beam based on the target position identified by the identifier.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is based upon and claims the benefit of priority from Japanese Patent Application No. 2017-244073, filed Dec. 20, 2017; the entire content of which is incorporated herein by reference.BACKGROUND OF THE INVENTIONField of the Invention[0002]Embodiments described herein relate generally to a medical apparatus and a method.Description of Related Art[0003]Therapeutic devices which irradiate a patient (object) with a therapeutic beam such as a heavy particle beam are known. There are cases in which a lesion of an object, that is, a spot to be irradiated with a therapeutic beam moves due to respirations, heartbeat, intestinal movements, and the like (hereinafter, these will be collectively referred to as “respirations and the like”). As a therapeutic method suitable therefor, a gated irradiation method and a tracking irradiation method are known.[0004]When a lesion which moves due to respirations is irradiated with a therapeutic ...
